Abstract: On the separation of acrylic acid from reaction gases from the oxidation of propylene or acrolein a countercurrent absorption is carried out with at least 8 parts by weight of carboxylic ester per part by weight of acrylic acid contained in the reaction gas, the dissolved acetic acid and the dissolved water are substantially completely expelled from the resulting absorption solution at elevated temperature by means of inert gases, the loaded inert gases are passed to the countercurrent absorption for the recovery of the acrylic acid contained therein, and the acrylic acid is distilled off under reduced pressure from the carboxylic ester solution which is free from acetic acid and water.

Abstract: Medicinal white oils and medicinal paraffins are prepared from petroleum fractions containing aromatics and nitrogen, oxygen and sulfur compounds, e.g. light and heavy atmospheric gas oils, vacuum gas oils and residues, which have been pretreated in a first stage by acid treatment or catalytic hydrogenation, by hydrogenation in a second stage over a nickel-containing catalyst under from 50 to 200 bar and at elevated temperatures, by a process in which the catalyst used in the second stage and present in the oxide form is reduced with a hydrogen-containing gas, passivated and then again activated with hydrogen, before the hydrogenation to medicinal white oils or paraffins is carried out.

Abstract: In the oxidation of .alpha.-olefins in the gas phase to a, .beta.-olefinically unsaturated aldehydes with molecular oxygen in the presence of an inert gas using a catalyst containing molybdenum and bismuth with elements as oxides or mixed oxides at from 280.degree. to 450.degree.C, a content of indium and/or lanthanum as oxide or mixed oxide results in an improvement in the conversion and/or activity and/or life of the catalyst.
